Beitl-lr'nown that I, C's'shnss R. PBDDLE, of Terr'eHaute, in the couhty'ofVigo, and Stateof as, have invented a new and'improvedPneumatic Brake forRailroaLd Cars; and I do hereby declare. that the following is' a full, clear, angle'x act description thereof, which will euable others skilled in the art to'make and it i use the same, rei'erencebeinghad tothe accompanying drawingsgforming' part of this specificatiomin which Figurel l is a side view of a locomotive and a side sectionahviewpf a. car, taken in the line a; 2:, fig. 2, having my invention applied to them. i i i Figure 2, a. plan or top view of thej-same. h i 1i Figure 3, an enlarged detached vertical sectionof the means by which the pow er'is applicdto the brakes. it Figure 4, an enlargeddetached vertical section of the steam chest and cylinderiof silocomotive;

This invention relates to a new and improved meatisfor operating the brakes of railroad cars by compressed air forcedinto the air cylinders :underneath the eat-s, by the locomotive, without-any cssentiali modification of the working partsof' the latter, a'valvesmd air pipe being.simply connectcdf'to the stcam fchest zof the steam cylinder. The objcctof the invention is to obtains. simple and e'conomical'ineans foroperating simultaneously";

i the brakes of allthe cars oi a train, and placing the brakes under the complete control-hf the engineer; I

A represents a locomotive; B one of the steam cylinders thereof, and the stenm; chest. These parts may) be constructed and arranged in the ordinary manner,a nd therefore, do not reqnire fh specioldcscriptionq 011 the top of the steam chest (1 there is a. tube, D, to which a. pipe, E, issttach'e'd, audwithin'the tubeDthere is t a. valve, F, by which the pipe E may be made to communicateiwith the ates-m chestfor be out ch therefrom when-desired; represent the fruclgs of a. car attachedt-o the locomotive by any suitable or alpprov'ed coupling. and H is a. pipe which is seeuredin alon'gitu dinal position under the hott omor bed Iof the cat'body, the pipe H being. connected by a. flexible tube, J, with thehpipe E, so that said pip esEf I-Imay cgimmuhicate with each other, and dueallowance made for the variation thedcngth of space between the locomotive ands, car, under the draught movement of the same 'and dneallowsnce also made for lateral pley of the cars end locomotive. "K is a cylinder, secured in s. vertical position at the centr c of the bed ofibottoin I of ,thecar, ,hnd having a piston, rL, 'iitted withinit, the rod M oi seid piston passing down through theilower end of cylinder 35K, and having a lever, 'N, pivoted centrally to its lower end, as shown clearly in 1 and 3. ;To each end of the lever N there is connected, by a pivot, a, a roll, 0, theupper ends of whichfare pivo'tedto one end right-j angular levers PP, theifulcra b of which are on the 011' bed or bottom I. The opposite: ends of ,the lovers 1 are connected byrods c c to levers Q, one end of which has the ordinary hsud b rake chains Rnttnched the opposite ends connected by rods '11 d to brake levers S attached to the outer shoe bars'T, the lowers i the levers-S being connected by rods e to the inner shoe bars. T. .(See fig. 1.) Allgthe 'cars of a trig supplied with theparts abovedescl ibed,and their pipes connected by flexible tubes.

r The operation is as follows: When the t'raiujs in motion, and itis desired to 'xstop, the engineer shuts ofii] the steam, and opens the valve]? in the. top of the steam chest C, and reverses, the motion of the slitle valve U i in the steam chest 0 by this means eir is drawn .into cylinder B through the exhaust passage f, the piston g, in the steam cylinder'B, worlsingwf course, under the momentum of the locomotive, and air, forged through, the steam chest C into the pipe E, and thence into pipe H, (see red arrow s,) and the piston Llin theaircy'liniler K raised under the pressure of the air. with the piston L the lever is also of course raised, and the levers i P P actuated, and the brakes applied, as willbe reudilyseenl This arrangement, it willj be seen, not only causes the train to be stopped by the application of the brakes, but also by aback pressure on' 'thej pistonsmgn and the invention admits of the brakes bei nghpplied by handin the usual'way whenever required; Having thus described my invention, I claim as new, and'desire to secure byLettrsPntent-d- I i The combination of the 'steamg cylinders,fsteam pipes, and steam chests of a locomotive with air pi'pesE g extending the whole length of a. train of I care, the volvesF in the steam chests, and'th e air cylinders K, provided with pistons L, connected withthe brake mechanism of the'cars, to opersite in thefmauner substantially as and" for the purpose set forth. I i p i i 1 i i i I also claim the leverlN connected to, the rod M of. piston L, and to the bent or rilght-angular lvers P P, to which the rods 0 c of the levers Q are connected, for the purpose of transmitting the power tothe brakes, substantially as shown and described. r 3 i 1 CHARLES, R.
